When thethermostat cut out point is reached, the circuit to the liquid line solenoid is opened de-energizing thesolenoid, causing the compressor to pump down. When the compressor pumps down to 20-25 psi the lowpressureswitch opens and power is terminated to the compressor.Defrost TypeDefrost scheduleDefrost terminationFan terminationElectric6 defrost periods per day for 15 min.12.8*C.12.8*C.Typical component SettingsController cut-outDifferentialTXVPressure switch-6.0*C.3K4*C. superheatPL cut out 25psi cut in 60psiHP 350psi7
